MC312 2-Channel Solid State Amplifier
 
300 Watts x 2 Channels
27% increase in Dynamic Headroom compared to previous model
McIntosh Autoformers™
 
Prepare yourself for years and years of musical enjoyment with the MC312 Power Amplifier. A 300 Watt per channel stereo amplifier, the MC312 is a great choice to power virtually any home audio system. The full 300 Watts can be delivered to almost any speakers regardless if they have 2, 4 or 8 Ohm impedance thanks to our unique Autoformer™ technology.
Named Best Stereo Power Amplifier of 2019 by Secrets of Home Theater and High Fidelity. "This just may be all the amplifier you will ever need!"
 
The MC312 has received numerous improvements compared to our previous 300 Watt stereo amplifier. Most notably is that filter capacity has been doubled, which increases dynamic headroom an impressive 27% from 1.8dB to 2.3dB. This increase means the MC312 will be even better suited to handle wide dynamic swings in your music. Distortion prevention and bass performance also benefit from the increased filter capacity.
 
"A component that makes you want to listen to as much music as possible, such as the MC312, is what it is all about... It is perhaps the finest, most sophisticated amplifier I have heard in its price range in my system." - NOVO Magazine
"When the hairs on your arms rise during a listening session, and you get a huge grin on your face, you know that (a) you're having a tremendous amount of fun, and (b) you're listening to true reference-quality equipment." - Secrets of Home Theater and High Fidelity
 
While still looking very much like a McIntosh, the MC312 has received some key design updates. Direct LED backlighting now illuminates the front panel for improved color accuracy. The audio output Autoformers still straddle the power transformer, but are now located in new enclosures that are capped by a single cover containing glass inserts that show the wiring diagram for each transformer.
